Huanyang vfd's which one, the FC series or HY series?

I am very frustrated with the unit but I'm kinda jammed up because I have a unicorn situation.
When I built my CNC I opted for a 110V spindle. Problem is that it's 3-phase 110V and there are no name-brand VFDs that output 110V 3-phase power. If I want to use a Teco or similar VFD I have to change out the spindle as well and run another 220V circuit in my shop. So probably a $500 swap.

you have to realize that many electronic things have issues.
Have you seen GM, Ford, Mercedes, Telsa, and others... All their electronics are PERFECT. No issues ever. :rolleyes:

If it's a pattern yea, it's a problem, but rare occurrences will happen in any electronic product. I know it sucks, but it happens.
The manufacturer should make it right. Push them for that.
 
Indeed, there are many (Hitachi, Teco, etc.) but I find the very difficult to find for some reason. I'm even in Toronto where you'd think finding stores to supply VFDs would be easy but this doesn't seem to be the case and most of my attempts to inquire from stores result in no responses. Might just have to eat the cost of ordering from the States. :(

Yeah, I'm in the ASIC industry...failures happen. That's understandable. And it's really my fault that I didn't check the VFD (other than power it on) to make sure everything was functional. At the time, there was no easy way to ascertain that it was all working other than it could be powered up and looked like it was "functional." I talking to Huanyang through Amazon hoping they'll be gracious and just send me a replacement but it's not looking too hopeful so...lesson learned. :(

Order from https://www.emotorsdirect.ca/
I have bought a bunch of stuff from them and they are fantastic to work with.

Understandable. I'm also torn whether or not I want to give Huanyang another shot (probably not). I bought the spindle and VFD kit almost two years ago but life took a turn and I had to set it aside. I only now got it all set up and have discovered that the thing can't retain its programming. Unfortunately, Huanyang is the cheapest thing going (which I guess makes sense) so I could roll the die again (this time I would be backed by Amazon) or just go for something better (what I'm leaning towards).

No, they are not the cheapest thing going. I researched a lot of them, and you can get one for half the price.
So waiting a long time from purchase to install is never a good idea. Even American companies won't warranty from your install date, only the purchase date.

sorry you had a problem, but your opinion is based on your anger... Why did you wait so long to install it? 2 years.. that's not their problem, it's yours.
 
No, I'm not really angry. I totally acknowledge that it's my fault for not testing it out within the 1 year warranty. For me, I can only really work on this thing during free time and having to source all the parts including the VFD cables and the interface to the controller etc. takes time. Even if I tested it out without everything fully complete, I would have programmed it, seen that everything was working and then set it aside while building everything else. And the problem only manifests itself after the VFD is powered off for a couple of days. Usually, it retains its settings if it's powered back on within a day or so.
 
mine is never on unless I am using it. I have been good. being someone in the industry, I would think you can find the chip that stores the data, and replace it.. maybe?
 
Well, it took 2 years to hook this thing up. How long do you think it's going to take to figure out which chip (assuming it's marked and even accessible) is being used to store the settings and then the source the chip, desolder the and resolder the chip. You could almost certainly do it with enough time and effort but that's not me.
 
Most of these inexpensive VFD's are not made to be repaired, and there may be certain elements such as shelf life that can also lead to failure like the electrolytic capacitors. Without an EE background and a schematic, I wouldn't waste time on figuring out the parameter memory loss and also knowing the means which parameters are stored when power is disconnected. I have not been a big fan of HY, or similar generic VFD's mostly because they are the only ones that I see consistent reports (and my own experience) of DOA or iterative failure over time. Most people feel, well they are cheap enough, I will just buy another one is it fails. Most main stream brand VFDs have a MTBF of 20-25 years, I have only seen a few failures and these I attributed it to user error. Frequent on/off power cycling or voltage surge/lightening strikes.

The Automation Direct GS20/GS21 VFD's are relatively inexpensive, they have a good track record as to reliability/durability, have readable manuals and very good tech. support/warranty support. There are various models. Teco models have almost doubled in price the last 3-4 years, they are simple and work well, but the GS21 offers more at less cost. Model/functionality depends on the application and budget. Since I am often building/helping others withe VFD installs or issues, I do not put in the effort to work on those VFD's that I have had eitehr reliability issues in the past or their paramter sets/manuals are very limited. Better VFD's also seem to function better with a wider range of motors/types.
